Edible gelatin microwave sterilization equipment is a kind of food sterilization equipment which uses microwave to sterilize. The biological effect of microwave sterilization equipment for edible gelatin on cells is that microwave electric field changes the potential distribution of cell membrane cross section, affects the concentration of electrons and ions around the cell membrane, thus changes the permeability of cell membrane, resulting in malnutrition, abnormal metabolism, dysfunction of cell structure and function, growth and development are inhibited and death. On the other hand, insects and fungi in edible gelatin can also be heated by microwave energy absorbed by molecules under the action of microwave. Thus, proteins in vivo are affected by both non-polar thermal motion and polar rotation, and their spatial structure is changed or destroyed to denaturate their proteins. After denaturation, the solubility, viscosity, expansibility, permeability and stability of protein will change significantly, and lose its biological activity.
Edible gelatin is a kind of fat-free high protein, a natural nutritional food thickener, and a strong protective colloid. It has strong emulsifying power. It can inhibit the agglomeration of milk, soymilk and other proteins caused by gastric acid when it enters the stomach, which is conducive to food digestion. Microwave sterilization is the result of the combination of thermal and biological effects of electromagnetic field. The thermal effect of microwave on bacteria is to change protein, make bacteria lose nutrition, reproduction and survival conditions and die. The biological effect of microwave on bacteria is that microwave electric field changes the potential distribution of cell membrane cross section, affects the concentration of electrons and ions around cell membrane, thus changes the permeability of cell membrane. Bacteria are malnourished, unable to metabolize normally, cell structure and function are disordered, growth and development are inhibited and death. In addition, microwave can make bacteria grow normally and reproduce steadily. Nucleic acid RNA and deoxyribonucleic acid DNA are relaxed, broken and recombined by several hydrogen bonds, which can induce genetic mutation, chromosome aberration or even breakage. The sterilization process of microwave sterilizing equipment for edible gelatin is thorough and comprehensive, providing various types of microwave sterilizing equipment selection scheme and budget quotation.
